Remedy
Power up all ISMs
simultaneously and start
automatic system configuration.
Check HLC.
Check solar parameter T2
Is thermal disinfection active?
Check connection.
Check system configuration for
hot water system or start
automatic system configuration.
Check system configuration for
heating circuit x.
Identify incompatible BUS
device and remove from the
system.
Set IPM for cylinder to coding 3
or higher.
Check system layout, check
system configuration, modify if
necessary and set parameter
again.
Remove the temperature sensor
and insert a coding plug if
necessary.
Check temperature sensor (T
and replace if necessary.
